I have created an Android emulator (Android Virtual Device), but I am unable to find out the SD card I have built during creation of this.
I have used the following procedure.
Android Studio 3.4.1
View>Tool Windows>Device File Explorer
refer to image below
To install apk manually: copy your apk to to sdk/platform-tools folder and run following command in the same folder
adb install apklocation.apk
DDMS is deprecated in android 3.0. "Device file explorer"can be used to browse files.
To install apk in avd, just manually drag and drop the apk file in the opened emulated device
The same if you want to copy a file to the sd card
